Obviously a gold digger situation, as they are 34 years apart in age, but not as blatant as you think. His wife is either 33 or 34. A lot of those pictures you see of her are filtered, plus she looks young for her age.
It appears worse because Scott is 67 and looks it, and she appears youthful, so the whole thing screams a combo of "dirty old man" and "gold digger".
However, the whole thing has fallen apart, as they announced in March that they are separated after just 2 years of marriage. Big shocker, I know.
Adams is a right-winger who has recently drawn the ire of some of his former MAGA fanboys because he has come out against some of the popular alt-right positions, especially when it comes to COVID and vaccination. At the same time, Dilbert has been dropped by a bunch of publications because the wokes have complained about Adams, so basically he's getting it from both sides right now.
He could have just stayed quiet and continued to make fun of ridiculousness in office settings, and everyone would have continued loving him.
